Learn more about machine vision! In our knowledge base we are explaining key technical terms about image processing. We give you an overview to topics like 3D machine vision or the established standards like CameraLink, GigE Vision or GenICam.
All images from lenses suffer from intensity variation from the centre to the
edge of the image. As this can affect the suitability of a lens for an
application, it is often necessary to examine the performance of a lens for
this behaviour, which is known as vignetting.
Machine vision is used for a diverse range of tasks in a wide range of markets. This diversity of application requirements drives the need for a wide range of vision systems to achieve a solution that is not only cost effective but also delivers the required features. This section outlines the basic choices in terms of hardware and software at a systems level to enable this optimum solution to be defined. Further information on the software tools can be found in the software section.
Many system integrators and advanced vision system developers value
the flexibility and openness of PC vision systems and develop their
individual software solutions using imaging libraries and high level
programming languages. More information about this approach is to
be found in the software section.
In most cases the vision system needs to be integrated with the
production system or machines programmable logic controller (PLC).
Inspection results should be directly transferred to the control system
to enable immediate reaction.
As the complexity of inspection applications can vary considerably it is important that the chosen solution fits the project requirements. A high level of flexibility will allow easy adaptations for new tasks that might occur later. Considering possible future needs should form part of the specification phase.
The first step when embarking on any project is to make sure that the
proposed solution is feasible. If you have some experience with vision
systems this may be quite straightforward, but if your knowledge is
limited, you may need assistance to estimate the technical and financial
implications. We can help with sample evaluations and we also run seminars which include sample evaluation workshops. These events
run regularly throughout the year.
